NAME

cfengine - network configuration engine

SYNOPSIS

/usr/sbin/cfengine [options]

DESCRIPTION

cfengine is a language based system specifically designed for testing
and configuring unix-like systems attached to a TCP/IP network. You can
think of cfengine as a very high level language -- much higher level
than Perl or shell. A single statement can result in many hundreds of
links being created, or the permissions of many hundreds of files being
set. The idea of cfengine is to create a single file or set of
configuration files which will describe the setup of every host on your
network.
cfengine runs on every host and parses one file (or file-set), the
configuration of the host is checked against this file and, if desired,
any deviations are fixed. cfengine reads a configuration file called
cfengine.conf in a directory pointed to by the environment variable
CFINPUTS. cfengine performs host integrity and security checks as well
as installing and repairing system configuration.

COMMANDLINEOPTIONS

-a (--sysadm) Print only the name of the system
administrator then quit.
-b (--force-net-copy) Forces net copy even if remote server is
localhost
-c (--no-check-files) Do not check access rights on file systems
-C (--no-check-mounts) Check mount points for consistency. If this
option is set then directories which lie in
the ”mount point“ area are checked to see
whether there is anything mounted on them.
-d (--debug) Enable debugging output. (parsing -d1,run,
-d2, lite -d3)
-D (--define) Define a compound class symbol of the form
alpha.beta.gamma.
-e (--no-edits) Suppress file editing.
-E (--enforce-links) Globally force links to be created where plain
files or links already exist. You have to use
this in interactive mode and answer a yes/no
query before cfengine will run like this.
-f (--file) Parse filename after this switch. By default
cfengine looks for a file called cfengine.conf
in the current directory.
-h (--help ) Help information. Display version banner and
options summary.
-H (--no-hard-classes) Prevents cfengine from generating any internal
class name information. Can be used for
emulation purposes.
-i (--no-ifconfig) Do not attempt to configure the local area
network interface.
-I (--inform) Switches on the inform output level, whereby
cfengine reports everything it changes..
-k (--no-copy) Do not copy/image any files.
-K (--no-lock) Ignore locks when running.
-l (--traverse-links) Normally cfengine does not follow symbolic
links when recursively parsing directories.
This option will force it to do so.
-L (--delete-stale-links)
Delete links which do not point to existing
files (except in user home directories, which
are not touched).
-m (--no-mount) Do not attempt to mount file systems or edit
the filesystem table.
-M (--no-modules) Ignore modules in actionsequence.
-n (--recon,--dry-run,--just-print)
No action. Only print what has to be done
without actually doing it.
-N (--negate,--undefine) Cancel a set of classes, or undefine (set
value to false) a compound class of the form
alpha.beta.gamma.
-p (--parse-only) Parse file and then stop. Used for checking
the syntax of a program.
-q (--no-splay) Switch off host splaying (sleeping).
-s (--no-commands) Do not execute scripts or shell commands.
-S (--silent) Silence run time warnings.
-t (--no-tidy) Do not tidy file systems.
-u (--use-env) Causes cfengine to generate an environment
variable CFALLCLASSES which can be read by
child processes (scripts). This variable
contains a summary of all the currently
defined classes at any given time. This option
causes some system 5 systems to generate a Bus
Error or segmentation fault.
-U (--underscore-classes)
When this option is set, cfengine adds an
underscore to the beginning of all hard system
classes (like _sun4, _linux etc.) This can be
used to avoid naming conflicts if you are so
injudicious as to name a host by the name of a
hard class. Other classes are not affected.
-v (--verbose) Verbose mode. Prints detailed information
about actions and state.
-V (--version) Print only the version string and then quit.
-x (--no-preconf) Do not execute the cf.preconf net
configuration file.
-X (--no-links) Do not execute the links section of a program.
-w (--no-warn,--quiet) Do not print warning messages.
